b. -6
c. 0
d. 24

Answer 1

To simplify the expression 9 - [3 + 2 × 3], solve the multiplication inside the brackets first, then perform the addition, and finally subtract from the number outside the brackets. The final simplified result is 0.

Step-by-step explanation:

The problem we need to solve is to simplify the expression: 9 - [3 + 2 × 3]. We will follow the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction).

1. First, solve the expression within the brackets by doing multiplication before addition: 3 + (2 × 3) = 3 + 6.
2. Next, complete the addition within the brackets: 3 + 6 = 9.
3. Finally, subtract this result from the number outside the brackets: 9 - 9.

The final answer is 0, which corresponds to option c.
